It's telling that Wolfram / Mathemetica doesn't even come up in a blog post like this, as the inventors of "the notebook". Jupyter took the concept to a whole new level, but the concept did originate in Mathematica 30 years ago!

The concept of literate programming, text interspersed with code, is older. Knuth mostly invented it, writing TeX, among other things, in it. Org mode even let you evaluate code blocks and store the output, or use it in future blocks.
